OOBBECTIVE SHOE AND ARCH SUPPORT THEREFOR.

Application fled Ianaary 28, 1926. Serial No. 84,265.

I. is invention relates to a corrective shoe and to a metatarsal arch support to be used in such a shoe, and it has for one of its ob jects to provide a. shoe havin built into it a novel arch-supporting mem r which will support both the transverse metatarsal arch and the longitudinal arch of the foot, and also to provlde a novel filler or sup rting member which may be readily built into the shoe and which is so constructed that its proper position in the shoe is determined by its relation to the inseam-receiving lip of the insole.

The features wherein the invention resides will be more fully hereinafter set forth and the novel features thereof will be pointed P out in the claims.

In the drawings, wherein I have illustrated an embodiment of my invention, Fig. 1 is a side view, partly broken out, of a shoe having my improvements embodied therein;

Fig. 2 is a bottom plan view of a shoe embodying my invention and having a portion of the outsole broken out to illustrate the manner in which the proper position of the arch-supporting member is determined;

Fig? 13 a top plan view of the supporting mem r;

Fig. 4 is a section on the line 44, Fig. 3;

Fig. 5 is a section on the line 5-5, Fig. 3;

Fig. 6 is a section on the line 66. Fig. 3;

Fig. 7 is a section on the line 7--7, Fig. 3.

In the drawings 1 indicates a shoe havin the usual outsole 2 and insole 3. Situate between the insole 2 and outsole 3 is a filler member 4 embodying my invention. Said member is preferab made of rubber so that it will be somewhat resilient and it has the special sha shown.

The outer e go 5 of said member, is convexly carved from the front 6 to the rear edge 7. The inner edge is convexly curved, as shown at 8, from the point 6 to an intermediate point 9 and is concavely curved from the point 9 to the rear edge 7, as shown at 10. At the front of the filler, the two convexly curved edges 5 and 8 meet in a point 6, while at the rear end, the sides 5 and 10 are separated somewhat from each other, thus forming the straight rear edge 7. This provides a member which is widest at the central portion and which tapers to a int at the front, while the rear end 11 io rms a sort of shank portion. The under face 12 of the supporting member or filler 4, or that side which rests on the outsole 2, is

edge 10 t made flat. The upper face, which rests against the insole. is rounded so that the member 4 is thickest at the center. The central portion of said member, indicated at 14 in Fig. 3, has a flat upper face and from the peripheral edge of this flat portion 14 the upper face curves toward the edges as shown at 15. This rounded or curve upper portion 15 of the filler member is such that on the convex edges 5 and 8, the top and bottom faces meet in a relatively sharp ed e, while at the concavely curved e filler member has an appreciable thickness, as shown best in Figs. 4 and 7.

In making a welt shoe having the im-. roved arch-supporting member therein said shoe will be lasted in the usual way and the welt 20 will then be sewed to the in-seamreceiving rib 21 b the in-seam stitches 22, all as usual in we ting operations. Before the outsole 2 is applied the arch-supportingFmember 4 is placed in position as shown in ig. 2 with the concave edge 10 of appreciable thickness resting against the inside of the in-seam receiving rib 21. The archsupporting member 4 1S placed so that the mt 9 comes just back of the ball of the cot and with the shank ortion 11 extendingflillp the shank of the cot.

e arch-supporting member is so designed that the curved edge 10 will fit the curve of the inseam-receiving rib at the shank and when it is placed as shown in- Fig. 2 with the edge 10 resting against the inner face of. the inseam-receiving rib said support will be properly positioned to give the desired supportnot only to the metatarsal arch but also to the longitudinal arch of the foot.

The inseam-receiving rib thus operates as a guide for correctly positioning the arch-supporting member and the ed 10 constitutes a positioning edge, thus acilitating the correct positioning of said member in the manufacture of the shoe.

Since the inseam-receiving rib 20 is approximately parallel to the edge of the outsole the concave edge 10 of the archsupporting member 4 will lie substantial parallel to the edge of the sole.

In the manufacture of shoes embodying this invention I ropose to use lasts 18 which are made with a slight hollow at the point where the suphport 4 is to be placed, as shown at 19 in ig. 1. The advanta e of this is that in the making of the shoe, t e

1 curved from the latter point outer sole will be laid flat, while the inner sole will be raised at the point where it passes over the metatarsal arch support and will thus be given the proper contour to give the desired support to the metatarsal arch.

I claim:

1. A welt shoe having an insole provided with an in-seam-receivingrib, an outsole and an arch-supporting member of resilient material situated between the insole. and outsole, the outer edge of said member having a convex curvature from the front to the rear and the inner edge being convexly curved from the front to a point intermediate the front and rear and concavely to the rear, the concavely-curved edge resting against and being positioned by the in-seam-receiving rib at the shank of the shoe, said member havin a flat under face resting on the outsole an being thickest at its central portion.

2. A welt shoe having an insole provided with an in-seam-receiving rim, an outsole and an arch-supporting member of resilient material situated between the insole and outsole, the outer edge of said member having a convex curvature from the front to the rear and the inner edge being convexly curved from the front 'to a point intermediate the front and rear and concavely curved from the latter point to the rear, the concavely-curvcd edge resting against and being positioned by the in-seam-receiving rib at the shank of the shoe, said member having a flat under face resting on the outsole and the central portion of the upper face also being flat, the marginal portions of said upper face tapering toward the under face and meeting said under face at the 4 from said mid position to the square rear end, said member having a flat under face and the central portion of the 1;]3138! face which is opposite the junction 0 the conwhereby the latter has an member for a shoe,

lie square rear vex and concave curves being flat, said ugper face curving toward the under face at t marginal portions and meeting the under face along the convex edges, the concawelycurved ortion of the edge being of a reciable tl iickness and constituting a positioning edge inseam-receiving rib of the shoe at the shank ortion thereof thereby to position the memer in the shoe with the forward pointed end thereof located in position to support the transverse arch of the foot.

In testimony whereof, I have signed my nameto this specification.
